Longer workweeks linked to rising obesity in new global study

A new study suggests that longer working hours may be linked to higher obesity rates. Researchers found that countries with extended workweeks tend to have more overweight populations. The findings have sparked calls for shorter working weeks to improve public health. Dr Pradeepa Korale-Gedara, from the University of Queensland, analysed data from 33 OECD countries. The research showed that a 1% drop in annual working hours corresponded to a 0.16% fall in obesity levels. However, the study did not confirm whether long hours directly cause weight gain, as income and lifestyle factors may also play a role.

Work-related stress and lack of time for exercise were highlighted as key contributors. High stress raises cortisol levels, which can increase fat storage. Many modern jobs also involve less physical activity than in the past. Campaigners argue that a four-day working week could help people make healthier choices. The 4 Day Week Foundation estimates that such a shift might reduce obesity in the UK by around half a million cases. Despite these calls, the UK government has stated it has no plans to introduce a mandatory four-day week on full pay.

The study adds to growing discussions about work-life balance and health. While no direct causation was proven, the findings suggest a possible connection between working hours and obesity. Advocates continue to push for policy changes, though no immediate government action is expected.
